I've done this before exactly 5 times on Windows 7 and once on 8 but this is my first time doing this on Ubuntu. In Windows I remember installing device drivers(?) but in /home/.flashtool/devices/ I see a "busybox" executable (.exe) file and am not sure whether I should run that with Wine to install on Ubuntu. Has anyone done this before and were successful on 14.04? What did I not do?

Please do not say "just use Windows if you know how to do it that way" because I wish to learn how to do it on Linux as well.

Thank you so very much for any/all help I get in advance. Please don't mind my bad English as it is not my first language.

Help! :silly:

Edit: I could not add links to this post as this is my first post. (I have the links to how I completed the above steps if anyone needs I will edit this post with links after 9* more posts for anyone who sees this post in the future for help.
